Abstract: A process for preparing a syngas from a methane comprising gas includes reacting the methane comprising gas with an oxidising gas at an operating temperature in the range of 1150 to 1370° C. by means of non-catalytic partial oxidation. A hot raw syngas mixture having a methane content higher than the methane content in a state of thermodynamic equilibrium at the operating temperature applied is passed through a bed of methane oxidation catalyst for oxidising methane with steam formed in the non-catalytic POX into carbon monoxide and hydrogen. The methane oxidation catalyst has at least one catalytically active metal supported on a refractory oxide support material where soot particles present in the hot raw syngas mixture are retained. The retained soot particles are converted to carbon monoxide. Soot depleted syngas is recovered in a state of thermodynamic equilibrium.

Abstract: The invention is directed to a process for the preparation of a syngas comprising hydrogen and carbon monoxide from a methane comprising gas, which process comprises the steps of: (a) reacting the methane comprising gas with an oxidizing gas in an autothermal reformer to obtain a hot raw syngas comprising carbon monoxide and hydrogen; (b) cooling the hot raw syngas resulting from step (a) to obtain the syngas, wherein step (b) comprises cooling the hot raw syngas by indirect heat exchange against the methane comprising gas used in step (a) and wherein sulphur is added upstream of cooling step (b). The invention also relates to a process for the preparation of hydrocarbon products in which a feed syngas is prepared in the process as described above followed by a desulphurization treatment and the desulphurized syngas is subsequently converted into hydrocarbon products in a Fischer-Tropsch process.

Abstract: The invention relates to a process for the preparation of a syngas comprising hydrogen and carbon monoxide comprising the steps of: (a) reacting a preheated methane comprising gas with an oxidising gas to obtain a hot raw syngas comprising carbon monoxide and hydrogen; (b) cooling the hot raw syngas resulting from step (a) to obtain the syngas by indirect heat exchange against water to produce saturated steam; (c) further cooling the raw syngas obtained in step (b) by indirect heat exchange against a methane comprising gas to obtain a cooled raw syngas and the preheated methane comprising gas for use in step (a), wherein: (i) steps (b) and (c) take place in a single cooling device for combined indirect heat exchange against water and against the methane comprising gas; and (ii) the preheated methane comprising gas obtained in step (c) has a temperature between 400 and 650° C.
